Maybe, in memoralization of your dad, you could go down to the sex shop...well, okay, tomorrow morning when you are there....pick up one of those 12" peters made of rubber and mount it to the motor. Run the control into it where you twist it one way to increase throttle and the other to decrease throttle.

Of course, you would need to rig it up where you pulled it out and pushed it in really fast to "choke" it

I think that would make pappabean a proud dead syphallian
